Task Summary

You need to:

SSH into the correct node: cka000055

Use kubectl to list all cert-manager CRDs, and save that list to ~/resources.yaml

Do not use any output format flags like -o yaml

Extract the documentation for the spec.subject field of the Certificate custom resource and save it to ~/subject.yaml

Step-by-Step Instructions

Step 1: SSH into the node

ssh cka000055

Step 2: List cert-manager CRDs and save to a file

First, identify all cert-manager CRDs:

kubectl get crds | grep cert-manager

Then extract them without specifying an output format:

kubectl get crds | grep cert-manager | awk '{print $1}' | xargs kubectl get crd > ~/resources.yaml

This saves the default kubectl get output to the required file without formatting flags.

Step 3: Get documentation for spec.subject in the Certificate CRD

Run the following command:

kubectl explain certificate.spec.subject > ~/subject.yaml

This extracts the field documentation and saves it to the specified file.

If you're not sure of the resource, verify it exists:

kubectl get crd certificates.cert-manager.io

Final Command Summary

ssh cka000055

kubectl get crds | grep cert-manager | awk '{print $1}' | xargs kubectl get crd > ~/resources.yaml

kubectl explain certificate.spec.subject > ~/subject.yaml

kubect1 get pods -o wide
